Description

Technical area

The invention relates to an elevator installation.

Technical background

The DE 10 2014 220 966 A1 discloses an elevator installation in which several cars are cyclically operated in a circulating operation, similar to a paternoster. In contrast to the classic paternoster, each car is driven independently of the other cars and can therefore stop independently of the other cars at any stop. Transfer units are provided to translate the cars from a vertical lane into a horizontal lane so as to translate the cars between different vertical lanes.

The German patent application 10 2018 205 592.0 discloses a method for mounting rails in an elevator installation of the aforementioned type. This takes into account the fact that the conversion units and the intermediate fixed rails must always have a correct alignment with each other. Among other things, the rails have a length compensation.

The EP 3 318 526 A1 discloses an elevator installation in which a car can be moved within a transfer station between two vertical shafts. The car is guided in the shaft by means of lateral guide rails. Here, guide rails are always arranged on opposite sides of the car. Essentially, in this type of rail guide, the center of gravity of the car is arranged between the guide rails. In order to allow a lateral movement of the car between the shafts, the car is moved together with the portions of the side guide rail between the shafts. In the transfer station, the laterally movable sections of the lateral guide rails are accommodated together with the car in a laterally displaceable cage ("elevator carriage guide 172" in FIG EP 3 318 526 A1 , Abs. [0035] and 3 ). However, when this cage is transferred between the shafts, the associated rail sections are not available for a vertical passage of another car through the transfer station.

Disclosure of the invention

It is an object of the present invention to provide an improved elevator installation. This object is achieved by an elevator system and a method according to the skin spans; Embodiments are the subject of the dependent claims and the description

• zumindest erste Fahrspur, welche in einer ersten Richtung, insbesondere vertikal, ausgerichtet ist, zumindest eine zweite Fahrspur, welche in einer davon abweichenden zweiten Richtung, insbesondere horizontal, ausgerichtet ist, und optional eine dritte Fahrspur, die insbesondere in der ersten Richtung ausgerichtet ist, insbesondere parallel zur ersten Fahrspur ausgerichtet ist. Die Aufzugsanlage umfasst ferner zumindest einen Fahrkorb, insbesondere eine Mehrzahl an Fahrkörben. Führungsschienen sind eingerichtet zum Führen des Fahrkorbs entlang der ersten und zweiten Fahrspur und optional der dritten Fahrspur, eine Umsetzeinheit zum Umsetzen des Fahrkorbs von der ersten Fahrspur auf die zweite Fahrspur und/oder von der zweiten Fahrspur auf die erste Fahrspur. Die Führungsschienen umfassen Rucksackführungsschienen, die zum Führen des Fahrkorbs zumindest während des Aufenthalts des Fahrkorbs in der Umsetzeinheit, und/oder zumindest während des Einfahrens des in die Umsetzanordnung und/oder zumindest während des Ausfahrens des Fahrkorbs aus der Umsetzanordnung eingerichtet sind. Die Führungsschienen umfassen ferner Seitenführungsschienen, die zum Führen des Fahrkorbs außerhalb dessen Aufenthalts in der Umsetzeinheit eingerichtet sind, insbesondere während in einer Vertikalspur zwischen zwei Umsetzeinheiten gefahren wird.

The elevator installation according to the invention comprises:

• at least first lane, which is aligned in a first direction, in particular vertically, at least one second lane, which is aligned in a deviating second direction, in particular horizontally, and optionally a third lane, which is aligned in particular in the first direction, is aligned in particular parallel to the first lane. The elevator installation furthermore comprises at least one car, in particular a plurality of cars. Guide rails are arranged to guide the car along the first and second lanes and optionally the third lane, a transfer unit for transferring the car from the first lane to the second lane and / or from the second lane to the first lane. The guide rails comprise rucksack guide rails which are arranged for guiding the car at least during the car's stay in the transfer unit, and / or at least during the entry into the transfer arrangement and / or at least during the extension of the car from the transfer arrangement. The guide rails further comprise lateral guide rails, which are arranged to guide the car outside its stay in the transfer unit, in particular while driving in a vertical track between two transfer units.

The combined use of side guide rails and backpack guide rails allows the utilization of the specific advantages. The backpack guide rails allow a simple, safe, rapid transfer of the car in a small footprint of the transfer unit. In addition, the transfer unit is immediately available after a conversion process for receiving or rectilinear passage of another car, since the guide rails do not move away laterally with the car from the lane. The side guide rail, however, are characterized during long and fast vertical driving and braking maneuvers by low role wear and low vibration on the rollers, since the transmission of the weight of the car is much more central, especially centrally or almost centrally.

In one embodiment, a side guide rail gap is provided, which is viewed in the direction of the first lane between two arranged adjacent, in particular vertically stacked side guide rails is arranged. This allows the transfer of the car in the lateral direction through the gap. Consequently, in the area of the converter arrangement, the lateral guide rail does not stand in the way of the sideways movement of the elevator car. In one embodiment, the gap height of the side guide rail gap is greater than a height of the car.

In one embodiment, an overlap region is provided. A car located in the overlapping area is guided both by at least one backpack guide rail and by at least one side guide rail. As a result, a safe transfer of the car between the side guide and the backpack guide is made.

In one embodiment, the car is always guided over the backpack guide rails and / or the side guide rails while driving in the first lane and in the second lane and when staying in a conversion unit of the car. This means that in the situations mentioned always one of the guides ensures a minimum guide, which increases the safety of the system.

In one embodiment, a conversion arrangement is provided for converting a car from a first lane, which is aligned in the first direction, to an adjacent third lane, which is also aligned in the first direction. Such a transfer arrangement comprises at least two transfer units, which are arranged in the second lane, and guide rails along the second lane, which are arranged between the two transfer units. The car is guided during the transfer between the two conversion units exclusively by backpack guide rails.

Description of embodiments

The 1 and 2 show parts of an elevator system according to the invention 1 , The elevator system 1 includes a plurality of lanes 2H . 2V along which several cars 5a - 5h are guided.

There are several, here exemplified two, vertical lanes 2V aligned in a first direction, along which the car 5 can be moved between different floors. Between the two vertical rails 2V are horizontal lanes 2H arranged along which the car 5 each within a floor is movable. Furthermore, the horizontal lane connects 2H the two vertical lanes 2V together. Thus, the horizontal lane is used 2H also for transferring the car 5 between the two vertical lanes 2V For example, to run a modern paternoster operation. It is in the elevator system 1 even more such horizontal lanes 2H provided, which connect the two vertical rails together. Further, more vertical lanes 2V be provided, which are not shown.

Along the lanes 2V . 2H are guide rails 21V . 22V . 22H . 22D provided for guiding the cars. The cars have guide rollers 51 on that in 1 Exemplary for the guidance on the rail 21V are shown.

The guide rails include backpack guide rails 22V . 22H . 22D , Backpack guide rails are arranged on a common side of the car. The car 5 , in particular the center of gravity of the car 5 , is always arranged cantilevered. The weight is transmitted via the introduction of bending moments on the backpack guide rails.

The backpack guide rails include fixed vertical backpack guide rails 22V aligned along the vertical track. The backpack guide rails include solid horizontal backpack guide rails 22H that go along the horizontal track 2H are aligned.

About a Umsetzanordnung 3 the car is convertible from one of the vertical lanes 2V to the other of the vertical lanes 2V ,

The Umsetzanordnung 3 includes two conversion units 30 , as well as a horizontal backpack guide rail 22H , About the conversion units 30 is the car 5 transferable between one of the vertical backpack guide rails 22V and the horizontal backpack guide rail 22H , The conversion unit 30 includes a rotatable backpack guide rail 22D ,

All guide rails are at least indirectly in a shaft wall 20 Installed. Up to here corresponds to the elevator system basically what in the WO 2015/144781 A1 as well as in the DE10 2016 211 997A1 and DE 10 2015 218 025 A1 is described.

The guide rails further include vertical side guide rails 21V , Two vertical lateral guide rails each 21V are on opposite sides of the car 5 appropriate. The focus of the car 5 is essentially (in y Direction viewed) arranged between the vertical guide rails. It goes without saying that in particular due to the design and / or loading the center of gravity of the car 5 at least in part not exactly between the vertical side guide rails 21V is arranged (in x Direction centered with the vertical side guide rails). Such vertical lateral guide rails 21V are used in isolation manifold in conventional elevator systems.

The peculiarity of the invention is now in an alternating arrangement of vertical lateral guide rails 21V and vertical backpack guide rails 22V along the vertical lane 2V , Such are the vertical backpack guide rails 22V in the field of sales units 30 arranged; the vertical side guide rails 21V span the area between two conversion units 30 ,

In the field of conversion units 30 are the vertical side guide rails 21V interrupted. In this respect, the conversion units 30 each in a side guide rail gap 21L arranged. Thus stand the vertical side guide rails 21V the side transfer of the car 5 not in the way.

A gap height H21L the lateral guide rail gap 21L is greater than the height H5 of the car. Thus, in the lateral transfer operation, the car fits through the side guide rail gap 21L therethrough.

In the field of Umsetzanordnung 3 allows the use of the backpack guide rails a speedy transfer of the car 5 between the vertical lanes 2V , It is unnecessary to use a kind of swinging cage, which receives the car during the transfer between the lanes, as in the introduction to EP 3 318 526 A1 explained.

The different situations in the rail guide of a car is described below with reference to 3a-e described. The cars shown there 5a - 5e correspond to the cars 5a-e in their respective in 2 illustrated situations. For simplicity, in the 3a-3e only the cars 5 and schematically illustrate those rails on which the car is guided in this situation. The associated roles are not drawn for reasons of clarity.

The car 5a is located in the 3a illustrated situation in an area between two Umsetzzeinheiten 30 , The car 5a becomes exclusively guided by the vertical side guide rails.

The car 5b is located in the 3b illustrated situation in an overlap area 24 in which the vertical lateral guide rails 21V and the vertical backpack guide rails 22V viewed in the direction of travel are overlapping seconded. The car 5b will now both through the vertical side guide rails 21V as well as through the vertical backpack guide rails 22V guided, resulting in a safe and comfortable transition from the side guide rails 21V on the backpack guide rails 22V allows.

The car 5c is located in the in the 3c1 and 3c2 situations in one of the conversion units 30 and thus also in the area of a side guide rail gap 31L , The car 5c is only by the rotating backpack guide rails 22D guided.

In the situation after 3c1 are the rotatable backpack guide rails 22D vertically aligned and aligned with the fixed vertical rucksack guide rails 22V (not shown). The car 5 can between the vertical backpack guide rails 22V and the rotatable backpack guide rails 22D be transferred.

In the situation after 3c2 are the rotatable backpack guide rails 22D F5 horizontally aligned and aligned with the horizontal backpack guide rails 22H , The car 5 can between the horizontal backpack guide rails 22H and the rotatable backpack guide rails 22D be transferred.

The car 5d is located in the 3d illustrated situation in a horizontal lane between two Umsetzzeinheiten 30 , The car 5d is made exclusively by the horizontal backpack guide rails 22H guided.

The car 5e is located in the 3e also shown in an overlap area 24 , The car 5b will now both through the vertical side guide rails 21V as well as through the vertical backpack guide rails 22V leading to a safe and comfortable transition from the vertical backpack guide rails 22V on the vertical side guide rails 21V allows.

As soon as the car is transferred, the rotatable backpack guide rail follows the horizontal rail 22H may have left, the rotatable rail 22D be turned back to the vertical orientation. Now, the next car can drive directly into the conversion unit, for example, to carry out the next transfer operation or for a vertical passage.

Once after moving the car, the rotatable backpack guide rail along the vertical rails 22V . 21V may have left, the rotatable rail 22D be turned back to the horizontal orientation. Now, the next car can drive directly into the conversion unit, for example, to carry out the next transfer operation or for a horizontal passage.

The overlap area 24 also allows a significant increase in the tolerances in the assembly of the vertical rails. The vertical rails are now not over the entire length of the lane (= shaft height) in a line. Heat induced changes in length of the vertical rails or setting of the building remain largely without effect as long as the overlap area 24 is sufficiently dimensioned.
